FRITZ SCHEEREN, 01'' FORD CITY, PENNSYLVANIA.

" Be. it known that I, FRITZ Ford City, in the county of Armstrong and State of Pennsylvania, have invented certain new and useful Improvements in Window'Screens, of which the following is a specification.

Thisinvention relates'to window screens and hasspecial reference to window screens of that type in whichv the'sc'reen is attached to the window sash and is 'mounted upon a .rollerdisposed at the upperoor lower end -gbyplacingi'in the-wallof the plate or board? below-the sill 6. The inner f side of each box isiclos'ed by a door 7 adaptof the window frame.

vision of an improved construction whereby the screen may be readily applied to the window and will'be out of the way so as not to interfere in any degree with the tordinaryadjustment of the sash.

The invention also seeks to provideimproved means for fastening the screen to the sashand also to improve the means for maintaining the screen in a'taut condition below or above the sash;

The several stated objects of the inven-' 'tion and such other'.-1incidental objects as will appear from'the following description, are attained in the construction illustrated vin the accompanying drawings, and the in- .vention resides in certain novel features a which will be particularly pointed out in the claims following the description.

In the drawings Figure lis a vertical {section of a window, showing portions of each sash and illustrating screens connected 1 with sashes in accordance with my invenin place; 5 is a detail perspective View,

tion, the sash cords and the guide pulleys for the same being omitted Fig. 2 is a detail horizontal section .of a portion of the window frame and sashes; Fig. 3 is a detail perspective view, showing the manner in which the screen is attached to the sash;

Fig.4 is an enlarged vertical detail section, showing one method of attaching the screen tothe sash in windows which are already showing parts of the structure illustrated in Fig. 4 detached but in their proper approximate positions. Fig. 6 is a detail perspective view of a portion of the screen guide shown in Fig. 4:; Fig. 7 is a view similar to Fig. 4, but showing a slightly difl'erentarrangement of the screen; Fig. 8 is a detail view of the roller; Fig. 9 is a detail perspective view of one end of the Specification of Letters Patent.

. roller; a detail perspective view of the end of the screen and the key which engages the same to connect it to the sash; Fig. 11 is a detail perspective view of the device for-windingthe spring in the roller.

In carrying out my invention, when the screen is to be. applied'to windows at the time the same are placed in the building, I provide boxes 1 and 2, respectively, above and below the window frame, the upper box I Patented J an. 11, 1916. Application filed February 25, 1915. Serial No. 10,561. a

being formed by inserting in the wall of the building a beam or plate 3 above the window lintel 4 and .the' lower box bein provide'd'. I

'edto swing into the room and held normally .in closed position by anyiconvenient form of latch, indicated at 8. The sashes, indicated at 9 and-10', are mounted in the window frame in the usual manner soas toslide between stops or beads 11 'and fit plane of the lower sashso as to distribute the strain equally to all parts of the sash". The] .upperslot 12, however, will ordinarily be located to one side ofthe central vertical plane of the sash-in order to avoid interference of the screen with the sash cord pulley. --Each screen is attached to and woundupon a roller 14 which is preferably mounted in brackets15 secured within the respective box 1 or' 2 These brackets 15 may be of any well known-construction and may be secured directly to the lintel 4 or the sill 6, but ordinarily it willbe found advisable to interpose blocks 16 between the sill 6 and the lower brackets. The screens maybe secured to the I'QSPGCtlWB rollers by any well known devices and may be of.

any preferred material, but will ordinarily be formed of wire netting. That edge of the screen which is free of the roller is reinforced by a metal strip or cap 17 which should extend across the entire width of the screen and is adapted to fit-snugly in groove 18 formed in the sash, this groove being formed in the upper end of the upper sash and in the lower. end of the lower sash, as will be readily understood. The cap or reinforcing plate may conveniently be of tion is duplicated on the two sashes with the exception that the key will lie in an inclined plane in the lower sash, whereas in the upper sash it will lie in a horizontal plane inasmuch as the lower sash is shaped to conform to the inclination of the sill.

The key 20 is provided with an opening or recess 22 in one end which is adapted to receive a withdrawing tool when it is desired to release the screen from the sash and vertical movement of the key away from the sash is prevented by a keeper 23which is secured in the sash and extends over the key, as shown most clearly in Fig. 3. As the key extends through the openings 19 and across the screen and is held to the sash by the keeper 23, it is evident that the screen will be securely attached to the sash and must follow the movements of the same, while at the same time the screen may be readily detached when so desired. The key is slightly below the Surface of the sash, While the keeper is flush with the same and consequentlv the sashmay be moved close against the li'ntel .or the sill of the window frame.

The window screen will preferably be somewhat wider than the sash and its side edges will project beyond the side edges of the sash and extend into slots or grooves 24 formed in the jambS, as shown most clearly in Fig. 2. The screen may extend entirely through these slots into the weight boxes formed in the sides of the window frame or may extend only partly therethrough," as illustrated, and? if so desired a metal lining 25 may be inserted in the groove or slot so' as to engage the edge of thefIsc-reen. Thisv construction effectually guides the screen in .its vertical movement and prevents buckling of the same so that it will be smooth and sightly at all times.

The rollers'may be of any desired length corresponding to the width of the screen and of the window frame in which they' are mounted. The roller comprises an outer cylindrical body 26 towhich the end of the screen is secured and one end of this cylindrical body 26 is bored out, as shown at 27 to receive a spring-supporting rod 28. This rod 28 is preferably a wooden cylindrical pin having its inner end engaging a socket or recess 29 in the outer cylindrical body and having its outer end bored to receive a pintle or-trunnion member 30. A metal cap 31 is placed over the outer end of this pin 28 so as .to prevent splittlng of the same and the pintle or trunnion 3.0 is inserted through a central -opening in the said capand into the end of the pin 28, after which it is secured'by a transverse key or pin 32. The outer'extrem ty of this pintle or trunnion is reduced and flat sided, as shown at 33, so that when it is engaged in the bear-' ing'bracket 15, it will be held against rotation. In the outer end of the cylinder 26, I secure a cap 34 which bears against the end of the pin 28 and the cap 31 fitted thereon and is provided at its center with a reinforcement or hub 35, the said reinforcement or hub and the said cap being rotatably mounted upon. the pintle 30. The said cap,

is provided with an opening 36' through which the wire of the spring 37 maypass and it also carries a pin or stud -38 to which the end of said wire may be secured. A11

outer collar or ring 39 is secured upon andaround the end of the cylinder 26 so as to reinforce thesame and prevent splitting thereof, the caps 34 and 39 together serving to very materially strengthen the end'of the roller. The spring 37 is wound around the pin 28 and has its inner end secured in a notch 40 in the inner end of said pin, while .the outer portion of the spring is carried through the opening 36 in the cap 34 and then around the hub or reinforcement 35, the" free end thereof being secured to the pin 38, as before stated. In order to prevent unwinding of the spring, while the roller is being fitted in place and-also to put the spring under the proper tension before it is mounted in its bearing brackets, I employ the 'key. illustrated in Figs. 8 and 11. This key comprises a winding member-41 having an angular opening-42 near one end which,

is adapted to engage the flat sided portion 33 ofthe pintle 30, and thisopening may be open-ended, as indicated in Fig. '8, or may have awall on all sides, as shown in Fig. 11.

Pivoted to the opposite end of the said winding member, is a lever and holding arm .43 which is provided with a tooth or spur 44 at its free end. After the winding member has been engaged upon the flat sided end of the pintle 30, as illustrated in Fig. 8, the arm 43 is swung away from the roller and utilized as a handle to rotate the key and the pintle and thereby transmit motion to the pin or rod 28 which will serve to wind the spring. After the spring has 'been placed under the desired tension, the arm 43 .is swung over to the roller and the tooth or spur 44 is impressed in the material of the roller, as shown in Fig. 8, so as to lock the roller to the pintle and, consequently, prevent unwinding of the spring. The key should be so placed upon the pintle that it will lie outside the bearing bracket when the roller is fitted in place so that it may then be and may be easily detached from'the roller and withdrawn. In small windows, a single spring will be found suflicient and the spring may be either a right handed or left handed spring. as is obvious, the tension under which the spring-is placed serving to hold the screen taut between the sash and the end of the window frame andtendijng n to wind the screen on the roller. In very large windows, it will be found advisable toemploy two springs, one at each end of the i roller and preferably one of the springs will be right handed while the other is left handed. In such event, of course, it Wlll be necessary to employ a winding and holdlng device at each end of the roller.

In Fig. 4, I have illustrated one method of applying the screen to a window in an .old building or. a building which is already standing. It being manifestly impractical and expensive to tear out a part of the wall,

so as to .provide the boxes for the rollers,

the brackets 45, which support the roller, are secured upon the inner sill 46v and a housing 47 is secured upon the sill so as to extend over the roller and protect the same against injury and also add to the sightliness of the window when equipped with the spring. The roller 48 may be fitted in the bearing brackets 45 or may be fitted in v notches cut into thejamb of the window and suitably shaped to hold the pintles or trunnions of the roller, as will be readily understood; The inner face of the sash is recessed, as shown at 49, and hooks 50 are secured in the said recess to engage openings 51 formed in the cap 52 on the edge of the screen. It will thus be readily seen that as the sashis raised, the screen will be drawn from the roller and will close the space between the lower edge of the sash and the top of the housing 47. To guard against buckling of the screen and hold the same smooth below the sash, I provide a guide strip 53, the lower edge of which is bent inwardly to provide'a slightly curved between the guide and the sill, as will be readily understood. Inasmuch as the screen is held smooth by this guide, it will wind upon or unwind from the roller easily without any tendency to catch and drag. The screen for the upper sash will be arranged in the same manner as the screen illustrated and described for the lower sash, except I that the bearings for the roller and the housing for the same will be secured to the under side of the lintel andat the outer lower sash of a window in a building which is already standing, it being understood that the screen for the upper. sash is a duplicate of the one shown, except that it is disposed 1 at the outer side of'the sash and below the lintel, whereas the drawing showsa screen mounted at the inner side of the sash and on the upper side of the sill. In this arrangement, the brackets 57 are secured upon the sill 58 and closer'to the front or inner edge thereof than is the case in the arrangement shown in Fig. 4. The housing 59 is also mounted upon the sill and extends over the roller and to the sash. The jambs 60 are cut-away at their lower ends to provide horizontal grooves in which the screen 61 may run, and immediately adjacent the sash the-upper walls of the said grooves are curved upwardly, as indicated at 62 so as to accommodate the flexing of the screen and also guide the same into a vertical plane and hold the same smooth when the sash is raised. The edge of the screen is reinforced. by the plate or cap 63 and to the said plate or cap I secure tongues 64: which engage hooks or similar devices 65 set in the recess 66 in the sash. In the arrangement shown in Fig. 7, 'as well as that shown in Fig. 4:, the housing is provided at its lower inner edgewith an inwardly extending flange or lip 67 which rests upon the upper surface of the sill and forms a steady support for the housing, and keepers 68 are driven into the sill so as to extend over the said flange, as clearly shown, and thereby retain the housing in place. These keepers or fastening devices may be readily withdrawn when it is necessary to remove the housing for any purpose.

It is thought that the operation-0f the device will be readily understood from the foregoing description taken in connection with the accompanying drawings. The

parts are all simple in their construction and are compactly arranged so that the improvements maybe readily applied to any window without detracting from the sightliness of the same or interfering in any manner with the ordinary use or adjustment thereof.

Having thus described the invention, what is claimed as new is:

1. The combination of a window sash having a groove formed in one end and having a keyway in the external surface of said end disposed at an angle to said groove and intersecting the same, a screen having its edge inserted in said groove and prowith said keyway, a key fitted in said key- -way and extending through said opening,

a keeper secured upon the sash over said key, and means for maintaining the screen in a taut condition. I a

2. The combination of a window frame, a sash slidable therein, bearings upon the frame, a roller having pintles adapted to engage said bearings, a spring connecting the pintle and the roller, and means for 'winding the spring and also locking the same to the roller whereby to prevent unwinding of the spring.

,3. The combination of a Window frame,

a sash slidable therein, bearings upon the frame, a roller having pintles in its ends adapted to engage said bearings, a screen holding member adapted to engage the ,roller whereby to lock the spring to the roller and prevent unwinding thereof In testimony whereof I aifix my signature in presence of two witnesses.
